This invention relates to the meansfor feeding material to working-:elements .which are intended to operate upon the material and Y has special referencey to the traveling belts whereby corn stalks are fed to thesnapping rolls of rcorn-husking machines. The object of the invention is to provide simple mechanism whereby the feeding table or belt may be shifted toward and from the snapping rolls of the machine so tov accommodate cornfstalks .and ears of different lengths and also to assist in clearing the rolls and the hopper of any excessive accumulations. The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.

In the drawings: y

The husking machine is illustrated in a more or less conventional manner and embodies husking rolls,'indicated at 1, and snapping rolls, indicated at 2, a hopper 3 being mounted upon the top of the-'machine in advance of the snapping rolls to guide the corn stalks to the rolls. yIn' Fig. 1, the Inachine is illustrated as'having sprocket gearing 4-mounted uponone side and including a sprocket wheel 5V secured uponv thev shaft 6' which carries the real` drum or roller ofthe feeding table or apron or belt 7 The feed- Y ing belt is carried by a rear drum or roller 8 'be' caused to rotate in unison.

or roller 9 carried by a shaft 10, each of said shafts having a sprocket pinion 11 Vthereon about which is" trained an endless chain 12 whereby the rollers orv drums 8 andv9 will- The shafts are rotatably mounted in brackets 13 secured to the inner sides of side bars or rails 14 vwhich lare slidably supported upon anglebrackets 15 secured to an upper frame bar ofthe 'huskingmachine and projecting inwardly through openingsH in the machine casing or frame as will beunderstood upon reference toFig. 4, the rails 14 obviously maintaining the bearing brackets in fixed spaced relation. The rear shaft 6. passes through a longitu- `dinal slot 16`in one side plate of the machine 'end oftthe pin or bolt 17 is pivoted one end of a .link 19` which extends vforwardly and has its frontend pivoted to the upstanding? shorter -arm V20 of an angle hand" lever 21' which is fulcrumed uponthe machine frame andis equippedwith a latch 22 cooperating with a holding rack 23 inan obvious manner.

In the operation o f the machine, the belt unevenly or other vcauses act to create,` an

that' theoperation ofthe snapping rollsis clogged.l Under AVthese circumstances, the i operator,who is'positioned upon aV platform 24 at the front end ofthe machine, rocksk the .hand lever 21and therebyv imparts a longitudinal bodily movement to the feedingbelt `asa unit so thatthefspace between the belt and the snapping rolls is' .increased andthe corn Vstalks thereby permitted to Apass more of one length it is desired to work uponstalks -7 travels continuously to convey the stalksv l kinto'thevhopper 3 and to thesna-pping rolls. 4Itsometimes happens that the stalks are yfed accumulation of the stalks'in the hopper so of greater or less length with correspondingly longer or shorter ears, and with the machines now generally constructed no provision is made to accommodate this variance in the length of the stalks and ears. With our present machine, however, the beltcan be shifted body as a unit longitudinally of the machine so that its delivery end will be closer to or farther from the snapping rolls and the opening or space for the passage of stalks and ears thus made larger or smaller according to the size of the ears and stalks. The opening may be regulated for dry or frozen stalks. It will be obvious that this unitary adjustment of the feeding belt is accomplished without stopping the operation of the belt. In Fig. 1, we have shown the belt as driven at its rear end or the end nearer the snapping rolls. We contemplate, however, driving the belt at the front end of the machine, and to accomplish this result it is necessary merely to provide sprocket gearing, indicated at 25 in Fig. 5, which will connect the front shaft l0 with a sprocket pinion 26 upon the fan vshaft 27 of the machine.

In this arrangement, it is found desirable to provide a belt tightener 28 on the side ofthe machine bearing constantly against the chain of the gearing. as illustrated. y

There is also comprehended within the invention an arrangement whereby the feeding belt may be adjusted vertically as well as horizontally. In Figs. 6 and 7 we have illustratedv such an arrangement wherein boxes 30 are secured upon a frame bar or beam 31 of the machine, and in these boxes are fitted posts 32 provided with series of openings33 therethrough. Mounted .in the sides of the boxes 30 are pins or bolts 34k which are en- Vgageable in selected openings 33 whereby the posts may be set at any desired height with respect to the frame bar 3l. Pivotally attaehed to the upper end of each post is a sup- Y porting arm 35 carrying at its upper end one end of a drum shaft 3S, it being understood that these posts and supporting arms are the weight imposed thereon.

duplicated at thetwo sides of the machine and that the shafts 36 extend across and carry drums over which are trained the feedingbelt 37. Side bars' or rails 38 are fitted to and 'extend between the shafts 36 so as to maintain `them in fixed spaced relation and resist the tendency of the feeding belt to sag under Sprockets 39 aresecured upon the shafts 36 and an endless 'chain 40 is trained around the said l sprockets so that the shafts and drums will rotate in unison, and motion is imparted to the drums and the feeding belt by sprocketl side of the machine in an obvious manner, a link 46 being pivoted to and connecting the hand lever and the adjacent arm 35, as clearly shown in Fig. 6. The hand lever and the parts cooperating therewith are mounted adjacent/che front end of the machine where the levermay be easily Vreached by the operator, and while we have shown the driving gearing as arranged to operate at the rear end of the belt, it may be disposed to actuate the belt at its front end, as will be understood. The arrangement just described obviously provides for a vertical adjustment of the feeding belt as well as a horizontal adj ustment thereof. It may be noted that with some constructions it is desirable to invert the illustrated arrangement so that the feeding belt will be supported in hangers corresponding to the posts 33 and the supporting arms 35 and such inversion of the mechanism is to be considered within the scope of the invention, and it is to be understood that the particular position of ,the snapping rolls is immaterial.

It is also to be understood that, while the invention has been herein disclosed with particular reference to a corn-husking machine, it is not limited to such machines but is applicable to all machines, such as threshing machines, in which it may be desirable at times to vary the distance between the feed table and the working elements.V

Having thus described the invention, we claim:

The combination of a support including parallel sidemembers, a hopper on the support, brackets secured to and projecting inwardly from said Side members, rails slidably resting von said brackets at the inner sides of the side members, drums'n'iounted at and extending between the corresponding ends of the rails, an endless feed belt having 'its ybights disposed around the respective drums,
